A five year supply contract was signed recently between the multicrystalline solar wafer manufacturer LDK Solar Co and the taiwan-based Solartech Energy Corp. For the five year period LDK Solar will deliver multicrystalline solar wafers to Solartech. The solar wafers are valued at approximately 224 million US dollars. “This agreement enables us to secure a significant amount of LDK Solar‘s high-quality wafers as we rapidly increase our production capacity. Solartech plans to double its capacity to 60 MW in November 2007 and to add 50 MW annually over the next two years to reach an annual production capacity of 160 MW in 2009,” stated Charles C. Chang, President of Solartech.
